There is no CD how to reinstall the system win7

Computer
The system will have different levels of problems and failures after a period of use. When the system cannot be repaired normally, you will usually choose to reinstall the system. Computers without a CD drive will make it impossible for users who use the CD to reinstall the system. Now let me introduce you how to reinstall the system win7 without a CD.

One, one key restore

1, first of all, it is necessary to download one-click restore software, such software version is more, and there is no official official website, so it is easy to download with The software of the virus must be paid attention to when downloading, and download it on the regular software website.

2, after the software is downloaded, you need to install it. Before you install it, you need to confirm whether it has been installed before, or it is installed Operating system
Whether it comes with this software, if it can not be repeated, because it will destroy the effect of one-click restore, confirm that there is no installation.

3, then the backup system is used for restoration. When backing up the system, make sure that the system is safe and able to run normally, because the restore operation will only be restored to the state when you backed up. Therefore, backup is very important. After the backup is complete, restart the computer and you will find an additional one-click restore option. You only need to reload the system in a single click.

4. The advantage of using one-click restore is that the operation is convenient and simple. You don't have to remember a lot of complicated steps. You can reinstall the operating system with a single click. The disadvantage is that you must operate it. The system is backed up when the system is complete, and only one one-click restore software can be installed on one computer, and the hard disk cannot be repartitioned.

Second, ISO format installation

1, this is a favorite installation method for many people, specifically using GHOST installation. This method of installing the operating system is also divided into two cases, one is hard disk installation, one is U disk installation. The hard disk installation needs to be in the case that the operating system is not completely bad, that is, when the operating system can be entered, the U disk does not have so many requirements.

2, look at the hard disk installation, you first need to download the ISO format operating system, and then extract the ISO file (you should have the decompression tool installed, if you do not need to download), then Run GHOST to install GHOST files in the same way as a normal GHOST installation.

There is no way to reinstall the system win7 without CD. The computer tutorial
learning network is only the one-click restore described above. The disadvantage is that it needs to be backed up before use. An intact operating system, if you have a one-click restore in the previously installed operating system, do not install this software again, this will cause the pre-existing "one-click restore" function to be invalid, and the installation will be completed. After the software, remember not to re-partition the hard disk. The partition change will cause the restore to fail, which may cause irreparable damage.
